INTERNAL- COMBUSTION ENGINE.

Application filed April 12, 1922. Serial No. 551,792.

To all whom it may concern:

Be it known that I, JOHN LUsc'oMBE MAR- T1N,-Jr., a citizen of theUnited States, residing at Newport News, in the county of Warwick andState of Virginia, have'invented certain new and useful Improvements inInternal-Combustion Engines, of which the following is a specification.

This inventien relates'to improvements in internal combustion engines,and the object is to arrange an automatic mechanism actuated by theclutch control whereby the timer mechanism may be retarded or advancedand the carbureter -throttled or opened simultaneously with theactuation of the clutch control means.

In the usual type of internal combustion engine the ignition and gas arecontrolled by levers attached to and working on a fixed quadrant securedto the engine at any convenient point. An impulseapplied to either ofthese levers is transmitted by a rod to the carbureter or timer and therequired adjustment is in this way made. A spring ratchet .pin in thelever bearing against the teeth in the quadrant prevents any accidentalmoif allowed to run at standard going ahead, or work-ing speed withclutch in neutral the virbrati'ons wouldbe detrimental to theconstruction of the boat I or bed and to the engine itself, and if downand clutch in to be advanced, let-- strain whileslowed with the engineslowed neutral, the clutch was tingth engine take the down the resultwould necessitates the adjustment of as and s ark when any-changes aremade in the c utch or reverse gear. M invention abolishes the necessityof any a justments at the'throwing in or .out of the clutch or reversegear, 4 y an. automatic ,co-operation' with the reverse or .clutch gearlever. The method used toaccomplish this, can be better explained, aftera description'of the parts.

In the accompanying drawings:

members 3 and ,be stalling. This lever n order to consisting prefer Thecasing preferably consists of front and back circular plates 1 and 4secured together by suitable bolts 5-5; The end members 3 and 4 are ofsuch a length as to form. an opening 6 at the top back circular plates 1and 2 are cut away and notchedas at 7 and 8 and directly below thenotched portions are semi-circular grooves 9 and 10. Slidably arrangedin each of these groovesstops each consisting of a forked member- '11,the lower ends of which areconnected by a transverse pin 12 which passesthrough 'the semi-circular groove in the side plates 1 .and 2. Thenumeral 13 indicates a pivoted stop'arranged at the up er end of theforked memberll, said stop w en in its lower position adapted to engageof the side plates. An abutment 14 extends laterally from the purposehereinafter described.

The numeral 15 indicates a shaft extending transversely through thefront and back plates 1 and 2, a portion thereof being restrictedas at16 forming a means for'securing the casing to a supporting bracket '17.Rotatably mounted-upon this shaft within the casing are two actuatinglevers 18 and 19 which extend upwardly through the open- 2 and end thenotched portion are two sets of adjustable forked member for a extremeupper ends with cars 20 and 21 whereby they may be. manually controlled,-the stops'll acting to limit their movement in either direction as maybe desired. The lower end of the lever .18 is connected to the valve ofthe carbureter by a link 22 while the lower end of the lever 19 is connected by'a link 23 to the timer mechanism.

As stated it is desirable to control these levers automatically by theclutch control mechanism and the carbureter when the engine is runn naccomplish this preferably use the following mechanism:

Pivotally mounted upon the shaft 15 bee tween-theactuating lever 18--19is a semicircular member 24. Thenum'eral 25 indicates a'semi-circularsegment notched as at 26 on its outer periphery. Carried by the properlycontrol the timer idle or under a load. To

1 3lbearing against-the outer edges of the therefore,

plate acting as a guide for the plate 29 when moved vertically. Anelongated opening arranged centrally of the plate 30 is preferablyprovided along one edge thereof with teeth 32 which mesh with the pinion29. The upper end of the vertically movable plate 30 is provided with aninverted \l-shaped slot 33. Extending horizontally oi the back plate 2is a slot 3-1 in which is slidably'mounted a block 35, carrying on theinner endthereof a roller 36 which is received in the inverted V-sliapedslot 33, and projecting laterally from the block 35 is a stud 37, whichis connected by a link 38 to the clutch control lever 39. Therefore, itwill be seen that when the block 35 is moved ineither direction theplate 24: is moved vertically, imparting a rotary movementto thesemi-circular tooth segment 25 which in'turn imparts a rotary movementto the actuating levers 18 and 19 which as described are connected tothe timer mechanism, and the carbureter. ,As mentioned, the actuatinglevers 18 and 19 are limited in their movement by the stop 11, thespring pressed dogs 27 and 28 permitting the toothed segments 25 torotate overa greater movement with respect to the actuating levers 18and 19 should the clutch control lever 39 be moved a sufficientdistance.

While I have shown this device as being controlled primarily by theclutch control lever it is obvious that the device may like-' wise beused in connection with reversible propeller mechanism whereby it wouldbe connected'with the prime controller means of such a mechanism.

It is obvious that this device may be applied to many different makes ofengines by more or less slight changes in construction, ll do not wishto limit myself to the exact structure as shown.

I claim:

1. A speed governing device for internal combnstion'engine comprising apivoted lerotary segment veibonhected to the fuel supply, a pivotedlever connected to the timer mechanism, a having engagement with saidpivoted levers, said segment being connected with the clutch controlmechanism whereby the said pivoted levers are simultaneously actuatedupon the movement of the clutch control mechanism.

2. An automatic controlling means for internal combustion enginescomprising a casing, actuating levers pivotally mounted therein,connecting link connecting said levers to the fuel supply and the timermechanism, a rotary notched segment arranged between said actuatinglevers, spring actuated dogs carried by said levers and adapted toengage said'notched segment, and means controlled by the clutch controlmechanism whereby said rotary notched segment is rotated and arelatively rotary movement is imparted to' said pivoted lever.

3. An automatic controlling means for internal combustion enginescomprising a casing, actuating levers, pivotally mounted therein,connecting links connecting said levers to the fuel supply and the timermechanism, a rotary notched segment arrange between said actuatinglevers, spring actuated dogs carried by said levers and adapt-- ed toengage said notched segment, a pinion connected with said rotarysegment, a vertically movable member adapted to impart a rotary movementto said notched segment, and means connected to the clutch controlmechanism 'for actuating said vertical movable member.

4. An automatic controlling means fo internal combustion enginescomprising a gas ing, actuating levers pivotally mounted therein,connecting links connecting said levers to the fuel supp y and the timermechanism, a rotary notched segment arrange between said actuatinglevers, spring actuated dogs carried by said levers and adapted toengage said notched segment, a pinion connected to said rotary segment,a vertically movable member in engagement with said pinion, saidvertically movable member being provided with an inverted V-shaped slot,and a reciprocating member in engagement therewith and connected withthe clutch control mechanism, whereby the pivoted levers are movedsimultaneously.

In testimony whereof I affix my signature.
